While Iwata was battling cancer, he and Tsunekazu Ishihara of The Pokémon Company worked together to create a mobile game that was “traditionally Nintendo”, but for a new generation of gamers who played on smartphones.

That became Pokemon Go, which Iwata worked on in his hospital room, reportedly saying “I still have unfinished business.”

Pokemon Go was officially unveiled to the world in September of last year — just months after Iwata passed away.
